命令行 php mysqli 失败，但可通过 Web 服务器运行并在本地运行 [英] Command line php mysqli fails but works via web server and works in local

问题描述

我有一个 shell 脚本，它调用一个 php 脚本在解析文本文件后在数据库中插入记录.当它调用 PHP 脚本时，我收到找不到 mysqli 的错误:

I have a shell script that calls a php script to insert records in database after parsing text file. When it calls the PHP script I get errors that it cannot find mysqli:

PHP Fatal error:  Class 'mysqli' not found in /path/to/php/file.php on line 5

这在使用 Nginx 和 PHP-FPM 以及 Mysql 5.5.x 的 Macbook Pro 本地失败，在我将套接字参数添加到 mysqli 调用后，它在本地工作.这适用于本地数据库！

This failed in local on Macbook Pro with Nginx and PHP-FPM and Mysql 5.5.x and after I added the socket param to mysqli call, it worked in local. This worked with local db!

$mysqli = new mysqli("localhost", "user", "pass", "mydb", 3306, "/tmp/mysql.sock");

我部署到 Linux 服务器(安装了yum install php"和 PHP 5.3.x 的 CentOS6).我更改了与远程数据库服务器的连接，因此删除了/tmp/mysql.sock"，因为数据库未在此服务器上运行.

I deployed to Linux server (CentOS6 that has 'yum install php' with PHP 5.3.x) installed. I changed the connection to a remote db server so dropped the "/tmp/mysql.sock" because db not running on this server.

shell脚本调用php执行脚本:

Shell script calling php to execute script:

php -c "/etc/php.ini" -f "/path/to/php/file.php"

鉴于我没有在本地运行 mysql，如何让它识别 mysqli 库并执行.它在 CentOS6 上.我什至尝试将 mysqli.so 添加到 php.ini 文件并得到以下错误:

Given I am not running mysql locally, how do I get it to recognize the mysqli lib and execute. It's on CentOS6. I even tried adding mysqli.so to php.ini file and got following error:

[mike@app2 myapp]# php -version
PHP Warning:  PHP Startup: Unable to load dynamic library '/usr/lib64/php/modules/mysqli.so' - /usr/lib64/php/modules/mysqli.so: cannot open shared object file: No such file or directory in Unknown on line 0

感谢您帮助解决此问题.通常我会使用 mysql(query) 但需要 mysqli() 来处理一些准备好的语句和脚本中的其他位.

Thanks for any help resolving this. Normally I'd use mysql(query) but need mysqli() for some prepared statements and other bits in the script.

推荐答案

发现mysqli没有安装php，运行如下命令:

I found that mysqli was not installed with PHP and ran the following command:

>php -i

这返回了 phpinfo() 并没有发现 mysqli.然后我运行'yum'命令来安装php-mysqli:

This returned the phpinfo() and found no mention of mysqli. I then ran the 'yum' command to install php-mysqli:

>yum install php-mysqli

此后脚本成功运行.希望这能帮助其他可能遇到类似问题的人.

After this the script worked successfully. Hope this helps others that might run into similar.
